Screen Printing Process Guide
What exactly is Screen printing? What is the procedure or process behind screen printing? Screen printing methods basically require webbed mesh or a screen which is properly stretched with a stiff casing. The portions which do not require printing are properly blocked. For creating prints, the screen needs to placed appropriately on dry paper or the fabric. Then the ink is placed above it. The rubber blade helps in spreading the ink properly across the screen. The ink uniformly spreads to the places which have been uncovered so as to create a design or a print. This form of printing is ideal when it comes to flat surface printing.
Screen printing is a superb combination of preparing, installing and orientation. The preliminary steps involve usage of cutting tools so as to create the right designs. Some tools which are commonly used are art knives, multiple blades, scalpels and scooping knives but of course. These can be used effectively for creation of designs on polyester surfaces, multifilament nylons. It is important to have screen printing inks which would be helpful in the procedure. The blotting pens are used for blocking parts which need not be printed. The next process is to spread the ink with the help of rubber blades, spatulas and rubber squeegees. Once this procedure is through, the artist uses the special screen printing frames. Novices can use tapes or clamps to keep the article to be placed in its place so that it does not move. If you are using photosensitive screen printing films, garment printing machines or tabletop printers need to be used.
Once the process of printing has been effectively completed, the next procedure is to cure the ink. Curing the ink is done with specific equipments like a flash dryer, textile dryer and a drying board. Fabric cleaning brushes are used for cleaning the screen. Sometimes the ink stains are really tough to clean and a quick screen wash is advised. Instant screen openers are helpful in dissolving the inks and these are highly effective in opening the mesh once there have been two to three ink coats.
The latest trend is to pass the printed article through heating tunnels through a conveyor belt. This means the ink would dry quickly, so that the material can be packed and stacked immediately. In any case, the screen print items need to be dried well so that they last longer. For darker items, ideally a proper supportive base print would serve the best. For lighter base colors, white is preferred.
